Biweight correlation
WebDec 3, 2024 · Traditional correlation measures provided in NetCoMi are the Pearson correlation, Spearman’s rank correlation and the biweight midcorrelation (bicor). Bicor as part of the R package WGCNA [ 52 ] is more robust to outliers than Pearson’s correlation because it is based on the median instead of the mean of observations. WebA robust measure in PCA using Tukey’s biweight correlation to downweigh observations was introduced and the optimum breakdown point to extract the number of components in PCA using this approach ...

WebTukey's biweight correlation is based on Tukey's biweight function that relies on M-estimators used in robust correlation estimates. This approach is more resistant for outlying values as it examines each observation and down-weights those that lie far from the center of the data. Another important part in WebThe module-trait heatmap usually represents the correlations of the module eigengenes with traits. When that correlation is high, it means the eigengene increases with increasing trait. In a signed network (where all genes in a module are positively correlated with the eigengene) it will mean that (again if the eigengene-trait correlation is ...
